[bouchal-38]

Hello , i have a 4500 with 2 sup card, i upload the new firmware to the bootflash and also to the slaveboot flash,  when i do a "sho bootflash" or a "show slavebootflash" i can see them.

But i cannot reboot on this new ios.(the new ios should be: cat4500e-universalk9.SPA.03.04.00.SG.151-2.SG.bin)

sw00166#sho slavebootflash:

-#- --length-- ---------date/time--------- path

  1  115931176 Nov 14 2013 10:31:05 +00:00 cat4500e-universalk9.SPA.03.03.02.SG.

151-1.SG2.bin

  2  123162032 Dec 11 2013 10:50:51 +00:00 cat4500e-universalk9.SPA.03.04.00.SG.

151-2.SG.bin

539738112 bytes available (239439872 bytes used)

When i do a "Sho bootvar", everything looks good:

sw0066#sho bootvar

BOOT variable = bootflash:cat4500e-universalk9.SPA.03.04.00.SG.151-2.SG.bin,1;

CONFIG_FILE variable does not exist

BOOTLDR variable does not exist

Configuration register is 0x2101

Standby BOOT variable = bootflash:cat4500e-universalk9.SPA.03.04.00.SG.151-2.SG.

bin,1;

Standby CONFIG_FILE variable does not exist

Standby BOOTLDR variable does not exist

Standby Configuration register is 0x2101

sw00166#

Hi,

Compared it with my 4500s. The configuration register is different on my device.

This is what I have:

SLWG-IDC-4500A#show bootvar

BOOT variable = bootflash:cat4500-ipbasek9-mz.122-50.SG6.bin,1;

CONFIG_FILE variable does not exist

BOOTLDR variable does not exist

Configuration register is 0x2102

boot system flash bootflash:cat4500-ipbasek9-mz.122-50.SG6.bin

Looks like you need to specify the image to boot with the boot system flash command and change the register to 0x2102

Have a look at the table below.

Table 3-4     Explanation of Boot Field (Configuration Register Bits 00 to 03) 

Boot Field	Meaning
00	Stays at the system bootstrap prompt (does not autoboot).
01	Boots the first system image in onboard Flash memory.
02 to 0F	Autoboots using image(s) specified by the BOOT environment variable. If  more than one image is specified, the switch attempts to boot the first  image specified in the BOOT variable. As long as the switch can  successfully boot from this image, the same image will be used on a  reboot. If the switch fails to boot from the image specified in the BOOT  variable, the switch will try to boot from the next image listed in the  BOOT variable. If the end of the BOOT variable is reached without the  switch booting successfully, the switch attempts the boot from the  beginning of the BOOT variable. The autoboot continues until the switch  successfully boots from one of the images specified in the BOOT  variable.
